MILO W. KIBBE, OF LOS ANGELES, CALIFORNIA.

VALVESPRING COLIPRESSOR AND PLACER.

Application filed September 15, 1921. Serial No. 500,876.

To all whom it may concern:

Be it known that I, MILO W. KrBBE. a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Valve-Spring Compressors and Placers, of which the following is a specification.

My invention relates to a device for compressing and replacing compression springs that are associated. with the inlet and exhaust valves of internal combustion engines, the principal objects of my invention being to provide a relatively simple, practical and efficient apparatus that will greatly facilitate and expedite the time and labor ordinarily involved in compressing valve springs and the placing of the same in position upon the valve stems.

A further object of my invention is to provide a valve spring compressing and replacing device that isprovided with a number of adjustments in order that it may be utilized for compressing and handling valve springs of different sizes.

With the foregoing and other objects in view. my invention consists in certain novel features of construction and arrangement of parts that will be hereinafter more fully described and, claimed and illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view of a valve spring compressing and handling device of my improved construction.

Fig. 2 is a side elevational view of the forward cushion of the compressing device with parts thereof in section.

Fig. 3 is a front elevational view partly in section of that portion of the device that is utilized for gripping and holding the compressed spring while it is being positioned upon the valve stem.

Referring by numerals to the accompanying drawings which illustrate a practical embodiment of my invention. 10 designates a base. onthe forward portion of which is arranged a plate 11. carrying a substantially cylindrical block 12. and formed on top of said block. is a transversely disposed rib 13. having the upper portions'of its ends cut away to form a plurality of notches 14, and which latter is adapted to receive the lower ends of valve springs of diflerent diameters.

Seated in and proiecting upwardly from the center of rib 13, is a stem 15, which serves as a support for the coil spring placed on the rib 13. I

Projecting upwardly from the rear end of base 10, is a tubular member 16,and

formed through the upper portion of the .ferent elevations, by a pin 18 that passes through the apertures 17, is a rod 19, through which is formed a series of ape-rtures 20, any one of which is adapted to receive the pin 1.8,and thus. said rod may be secured in the tube 16 at diflerent elevations.

Pivotally connected toa transverse pin 21, that is seated in the upper end of rod 19, are the lower ends of a pair of links 22, the upper ends thereof being pivotally connected by a transversely disposed pin 23 to a bifurcated end 24:, of a lever, the rear portion of which is provided with a handle 25. Formed in the under side of the bifurcated portion of the lever. are notches 26. that are adapted. to engage pins 27, and which latter proiect outwardly from a short sleeve 28. that is arranged to slide freely upon a vertically disposed rod 15. If desired. the pin 18 and sleeve 28, may be conncoted to the lever by short chain sections such as 29 thus preventing said parts from becoming misplaced or lost.

The compressed spring engaaing and handling device comprises a pair of handles 30. that are hinged or pivotally connected to each other at points inte mediate their ends and arranged between the handles to the rear of the pointot pivotal'connection. is a spring 31. By this arrangement it willbe seen that outward pressure on the rearrpor tions of said handles tends to swing the forward ends thereof toward each other.

Formed integral with the forward ends of the handles 30. are vertically disposed iaws These screws also pass through keepers 38 that extend partially around the jaws and 34.

By virtue of the construction just described, the outer pair of jaws 3%, may be adjusted upon the inner jaws 32, so as to vary the distance between the pairs of lips or flanges and 35, and consequently enabling the device to engage and retain compressed springs of different lengths.

In the use of my improved device, the bifurcated lever is swung upwardly into a substantially vertical position and sleeve 28 is withdrawn l'rom rod 15, the spring to be compressed and engaged, is positioned in said rod, with its lower coil resting on a pair of shoulders on the ends 01" rib 13, after which sle'eveQS is repositioned upon rod 15 and permitted to move downwardly thereupon until it rests upon the usual washer that is carried by the upper end of the valve spring. The bifurcated lever is now swung downward until the pins 27 are engaged in the notches 26, and a further downward movement of the free end of the lever will compress the spring to the desired degree. \Vhile the spring is thus compressed, the rear portions of handles 30 are moved toward each other to spread the forward end of said handles apart,and the forward ends er said handles are manipulated so that they occupy positions immediately adjacent to and on opposite sides of the compressed spring, the rear portions of the handles 30 are now releasedto permit the jaws on the forward ends of the said handles to move toward each other and thus engage with the jaws, and when so positioned, the lips or flanges and 35, will be engaged over the ends of the compressed spring and consequently retaining said spring in its compressed condition. The biturcated handle is now swung upwardly and after sleeve 28 is withdrawn from rod 15, the compressed spring is removed from the rod 15, and by proper manipulation of the pivotally conne'cted handles 30, the compressed spring carried thereby may be readily positioned upon the valve stem and secured thereto in theusual manner.

The valve spring compressing and han' dling device of my improved construction is comparatively simple and may be easily and cheaply produced. It may be readily adjusted so as to handle springs of different length and device, and the use of the device is effective in saving much of the time and labor ordinarily involved in compressing and handling valve springs.

It will be understood that minor changes in size, form and construction of the various parts of my improved valve spring compressing and handling device may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim as my invention:

L-In a valve spring compressing and handling device, a support for a spring, a vertically adjustable member adjacent to said support, a lever fulcrumed to said vertically adjustable member and a sleeve loose- .y arranged on the support and adapted to be engaged by said lever.

2. A spring compressing device comprising a spring support, arod extending from the support. a sleeve slidably mounted on the rod, projections formed on the sleeve,

and a lever fulcrumed to engage the projections and move said sleeve for the purpose described.

3. A spring compressing device comprisin: a spring support, a member secured to and extendingfrom the support, an element slidablv mounted on the member, and a lever tulcruined to engage the element and move the latter on the member for the purpose described.

4. A spring compressing device comprising a spring support, a member secured to and extending from the support, an element slidablv mounted on the member. and a lever adiustablvfulcrumed to engage the element and move the latter for the purpose de scribed.

In testimony whereof I have signed my name to this specification.

MILO W. KIBBE.
